CAL TECH : NEW TECHNOLOGY TO DETECT EARTH'S PLATES BELOW THE SURFACE

CAL TECH : NEW TECHNOLOGY - EARTH'S PLATES 

Excerpts: Caltech researchers have developed a new method to study the earth's structure deep beneath the surface, at the boundary between Earth's brittle crust and the underlying mantle, a region called the Mohorovičić discontinuity—Moho for short.

.....On continents, the Moho can be found at depths ranging between 20 and 70 kilometers beneath the surface; in Southern California, the Moho is around 45 kilometers belowground. Attempts had been made to image it using conventional seismometers, but these efforts either yield low-resolution results, on the scale of tens of kilometers, or were prohibitively expensive. With the DAS method, researchers can easily observe the structure of the Moho over large regions at a resolution of a kilometer, providing a far more detailed look at this geologically important region.

SOUNDINGS - THE REMARKABLE STORY OF MARIE THARP, the GEOLOGIST WHO MAPPED THE OCEAN FLOOR

Just heard of this new book, which sounds exciting!  Marie Tharp dedicated more than 20 years of her career to the Lamont Geological Observatory.


Link to the author HALI FELT here!  "Her maps of the ocean floor have been called “one of the most remarkable achievements in modern cartography”, yet no one knows her name... Before Marie Tharp, geologist and gifted draftsperson, most people thought the ocean floor was a vast expanse of nothingness."

If you can't afford to purchase this book, be sure to ask your local library to buy a copy for circulation. 

DEAD SEA SINK HOLES SUCKING TOURISTS!

I like my "headline better than theirs..." Here the breaking news from Joseph Marks of the Seattle Times...

"These underground craters can open up in an instant, sucking in whatever lies above and leaving the surrounding area looking like an earthquake zone.

The phenomenon, Raz said, stems from a dire water shortage, compounded in recent years by tourism and chemical industries as well as a growing population. "This is the most remarkable evidence of the brutal interference of humans in the Dead Sea," he said.

The parched moonscape, famous as the site of biblical Sodom and Gomorra, is the lowest point on earth and runs more than 60 miles through Israel and the West Bank."
